2 2 BIOS setup progra m

This motherboard supports a programmable firmware chip that you can

update using the provided utility described in section "2.1 Managing and

updating your B IOS."

Use the BIOS Setup program when you are installing a motherboard,

reconfiguring your system, or prompted to "Run Se tup". This section

explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the configuration of your compu ter in the future. For example, you can

enable the security password feature or change the power management

settings. This requires you to reconfigure your system using the BIOS

Setup program so that the computer can recognize these changes and

record them in the CMOS RAM of the firmware hub.

The firmware hub on the motherboard stores the Setup u tility. When you

start up the computer, the system provides you with the opportunity to

run this program. Press during the Power-On-Self-Test (POST) to

enter the Setup utility; otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing

, or by pressing the reset button on the system chassis.

You can also restart by turning the syste m off and then back on. Do this

last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. Being

a menu-driven program, it lets you scroll through the various sub-menus

and make your selections from the available options using the navigation

keys.

The default BIOS settings for this motherboard apply for most

conditions to ensure optimum performance. If the system becomes

unstable after changing any BIOS settings, load the default settings

to ensure system compatibility and stability. Select th eLoad

Defaul t Se t t ings item under the Exit Menu. See section "2.7 Exit

Menu."

The BIOS setup screens shown in this section are for reference

purposes only, and may not exactly match what you see on your

screen.
